Monoterpenoid indole alkaloids from the fruits of Gelsemium elegans and their anti-inflammatory activities

Two novel monoterpenoid indole alkaloids (MIAs), gelsechizines A-B (1-2), along with four known ones (3-6) were isolated from the fruits of Gelsemium elegans. Compound 1 features a new carbon skeleton with two additional carbon atoms forming a 4-methylpyridine unit. Their structures with absolute configurations were elucidated by NMR, MS, X-ray diffraction and electronic circular dichroism (ECD) calculations. Compounds 1-3 showed significant anti-inflammatory effects in vivo and in vitro, which may be related to the inhibition of the trecruitment of neutrophils and macrophages as well as the secretion of TNF-alpha and IL-6. Preliminary structure-activity relationship analysis revealed that the beta-N-acrylate moiety plays an important role in the anti-inflammatory effect.

Combination of UHPLC-MS/MS-molecular networking approach and FTICR-MS for the metabolic profiling of Saccharomyces cerevisiae

Natural products are a reliable source of bioactive molecules and represent an industrial and pharmaceutical stake. Indeed, the model yeast species Saccharomyces cerevisiae is a well-known eukaryotic organism largely used as a biotechnological tool, but still a topical subject of study. In this work, the exploration of Saccharomyces cerevisiae is taken further through an untargeted metabolomics workflow. The aim is to enrich databases and bring new information about the standard S. cerevisiae strain in a given medium. Analytical methods and bioinformatics tools were combined in a high-throughput methodology useable to dereplicate many types of biological extracts and cartography secondary metabolites. Ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) analyses were carried out and spectral data were pre-processed to build molecular networks. Annotations were attributed to compounds through comparison with databases and manual investigation of networks. Ultra-high-resolution Fourier-transform ion cyclotron resonance mass spectrometry (FTICR-MS) brought additional information thanks to a higher dynamic range and enhanced UHPLC-MS/MS results by unveiling ambiguities and bringing accurate molecular formulae. Therefore, accurate and reliable annotated features resulted from the UHPLC-MS/MS data while FTICR-MS provided an overall cartography of metabolites thanks to van Krevelen diagrams. Various small molecules such as amino acids derivatives and indole alkaloids have been determined for the first time in this yeast. The complementarity of FTICR-MS and UHPLC-MS/MS for secondary metabolite annotation brought this new mapping of S. cerevisiae. (C) 2020 Elsevier B.V. All rights reserved.

Development of 2-oindolin-3-ylidene-indole-3-carbohydrazide derivatives as novel apoptotic and anti-proliferative agents towards colorectal cancer cells

Mitochondrial anti-apoptotic Bcl2 and BclxL proteins, are overexpressed in multiple tumour types, and has been involved in the progression and survival of malignant cells. Therefore, inhibition of such proteins has become a validated and attractive target for anticancer drug discovery. In this manner, the present studies developed a series of novel isatin-indole conjugates (7a-j and 9a-e) as potential anticancer Bcl2 and BclxL inhibitors. The progression of the two examined colorectal cancer cell lines was significantly inhibited by all of the prepared compounds with IC50 ranges132-611 nM compared to IC50 = 4.6 mu M for 5FU, against HT-29 and IC50 ranges 37-468 nM compared to IC50 = 1.5 mu M for 5FU, against SW-620. Thereafter, compounds 7c and 7g were selected for further investigations. Interestingly, both compounds exhibited selective cytotoxicity against both cell lines with high safety to normal fibroblast (HFF-1). In addition, both compounds 7c and 7g induced apoptosis and inhibited Bcl2 and BclxL expression in a dose-dependent manner. Collectively, the high potency and selective cytotoxicity suggested that conjugates 7c and 7g could be a starting point for further optimisation to develop novel pro-apoptotic and antitumor agents towards colon cancer.

Copper(II) and Nickel(II) complexes of the non-steroidal anti-inflammatory drug indomethacin containing aromatic chelating N,N-donor ligand: Synthesis and structural studies

Two complexes [Cu(indo)(2)(phen)(H2O)];Cu-1 and [Ni(indo)(2)(phen)(H2O)(2)]center dot 1.5H(2)O;Ni-1, were synthesized by the reaction of their respective metal(II)acetates with indomethacin (indo) [1-(4chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetic acid)] and a nitrogen donor heterocyclic ligand 1,10-phenanthroline (phen) in acetonitrile: water mixture (9:1 v/v), by refluxing at 80 degrees C for 3 h. The complexes were characterized by physicochemical, spectroscopic, and TG analysis. X-ray structural analysis showed that both complexes crystallizes in the triclinic space group P-1. Cu-1 consists of Cu(II) in square pyramidal geometry and coordinated to two monodentate indomethacin ligands, a bidentate 1,10phenanthroline, and one aqua ligand. Intermolecular O-H center dot center dot center dot O, C-H center dot center dot center dot O, C-H center dot center dot center dot Cl, Cl center dot center dot center dot Cl, and C-H center dot center dot center dot interactions in Cu-1 were responsible for the stability of the complex. Ni-1 is centrosymmetric and consists of Ni(II) in a distorted octahedral geometry, involving two trans monodentate indomethacin ligands, a bidentate 1,10-phenanthroline ligand, and two cis aqua ligands. There were two lattice water molecules outside the coordination sphere of Ni-1, that participated in extensive O-H center dot center dot center dot O interactions. The complex was further stabilized by C-H center dot center dot center dot O, C-H center dot center dot center dot pi, and pi…pi interactions. The monodentate coordination of the carboxylato oxygen of indomethacin ligand in the complexes was confirmed from the FTIR studies. TG analysis provided information on the stability and decomposition pattern of the complexes. (C) 2020 Elsevier B.V. All rights reserved.

The copper(ii)-catalyzed and oxidant-promoted regioselective C-2 difluoromethylation of indoles and pyrroles

A novel and efficient approach for the highly selective C-2 difluoromethylation of indole derivatives was developed by using sodium difluoromethylsulfinate (HCF2SO2Na) as the source of difluoromethyl groups and a Cu(ii) complex as the catalyst. Various substrates were well tolerated in this transformation and the desired products were obtained in moderate to good yields. Moreover, the late-stage C-2 difluoromethylation of bioactive molecules containing an indole ring was achieved in good yields. Generally, this reaction features excellent functional group compatibility, broad substrate scope and excellent C-2 selectivity.

Genome-wide characterization and expression analyses of the auxin/indole-3-acetic acid (Aux/IAA) gene family in apple (Malus domestica)

Auxin is a necessary phytohormone for fruit development, accompanying the whole process of fruit growth and development. The Aux/IAA gene family is one of the early auxin-responsive gene families. At present, there were few reports involved in Aux/IAA genes in the fruit, especially in apple. In our study, we identified 42 MdAux/IAAs, phylogenetic analysis showed that Aux/IAA proteins from apple, tomato, and strawberry were clustered into 5 groups, 42 MdAux/IAAs randomly distributed on 13 chromosomes. Additionally, a comprehensive analysis of Aux/IAA gene family was completed, including gene structures, conserved motifs, phylogenetic analysis, chromosome mapping, orthologous identification, selection pressure analyses, synteny analysis, and protein interaction. We also tested the expression of MdAux/IAAs in different tissues and fruit development stages using quantitative reverse transcription-polymerase chain reaction (qRT-PCR), we found that the most members of Aux/IAA showed higher expression in seeds compared within stem and leaves, indicating they may play a role in regulating fruit development. We also declared that the expression of Aux/IAA gene was not consistent in the pericarp and seeds at the same developmental stage, 3 MdAux/IAAs of the pericarp were upregulated over 20 fold at 90 d and 5 MdAux/IAAs of the seeds were upregulated over 40-fold at 90 d. It was MdAux/IAA23 that showed extreme up-regulated expression in both pericarp and seeds. This study proved that the Aux/IAA gene families may perform a different function in apple fruit development and ripening, more importantly, it provided a foundation for further exploring the biological function of these MdAux/IAAs.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 83-73-8, you can contact me at any time and look forward to more communication. Safety of Diiodohydroxyquinoline.

Biodiversity of Convolvulaceous species that contain ergot alkaloids, indole diterpene alkaloids, and swainsonine

Convolvulaceous species have been reported to contain several bioactive principles thought to be toxic to livestock including the calystegines, swainsonine, ergot alkaloids, and indole diterpene alkaloids. Swainsonine, ergot alkaloids, and indole diterpene alkaloids are produced by seed transmitted fungal symbionts associated with their respective plant host, while the calystegines are produced by the plant. To date, Ipomoea asarifolia and Ipomoea muelleri represent the only Ipomoea species and members of the Convolvulaceae known to contain indole diterpene alkaloids, however several other Convolvulaceous species are reported to contain ergot alkaloids. To further explore the biodiversity of species that may contain indole diterpenes, we analyzed several Convolvulaceous species (n = 30) for indole diterpene alkaloids, representing four genera, Argyreia, Ipomoea, Stictocardia, and Turbina, that had been previously reported to contain ergot alkaloids. These species were also verified to contain ergot alkaloids and subsequently analyzed for swainsonine. Ergot alkaloids were detected in 18 species representing all four genera screened, indole diterpenes were detected in two Argyreia species and eight Ipomoea species of the 18 that contained ergot alkaloids, and swainsonine was detected in two Ipomoea species. The data suggest a strong association exists between the relationship of the Periglandula species associated with each host and the occurrence of the ergot alkaloids and/or the indole diterpenes reported here. Likewise there appears to be an association between the occurrence of the respective bioactive principle and the genetic relatedness of the respective host plant species.

Mechanochemical synthesis, linear and nonlinear optical properties of a new oligophenyleneimine with indole terminal moiety for optoelectronic application

A quadrupolar D-pi-A-pi-D oligophenyleneimine with indole moiety as terminal group (OIC-I) obtained by a green method of mechanosynthesis was obtained. The molecular structure of OIC-I was elucidated by FTIR and H1 NMR spectroscopies. DFT and TDDFT studies show possible intramolecular charge transfer (ICT) processes and a hyperpolarizability value that suggest a nonlinear behavior, which was verified by Z-scan technique. The linear optical characterization of OIC-I using UV-Vis spectroscopy and fluorescence in solution and solid state exhibits a bathochromic effect by increasing the polarity of the solvent. According to data obtained by the Z-scan technique, OIC-I could be used as a saturable absorb material, and this feature can be applied in nonlinear signal filtering, optical signal processing, and mode locking devices. OIC-I has attractive linear and nonlinear optical properties, good processability in solution, and thermal stability for its potential application as a saturated absorber in optoelectronic devices.

Mycelial culture extracts of selected wood-decay mushrooms as a source of skin-protecting factors

Objectives This study analyzed the content of substances with cosmetologic properties in the extracts obtained from the mycelial cultures of Ganoderma applanatum, Laetiporus sulphureus, and Trametes versicolor. The effect of these extracts on the inhibition of tyrosinase and hyaluronidase was determined, and their values of sun protection factor (SPF) were calculated. Results The total amount of phenolic acids in the extracts ranged from 2.69 (G. applanatum) to 10.30 mg/100 g dry weight (T. versicolor). The total amount of sterols was estimated at 48.40 (T. versicolor) to 201.04 mg/100 g dry weight (L. sulphureus), and that of indoles at 2.90 (G. applanatum) to 16.74 mg/100 dry weight (L. sulphureus). Kojic acid was determined in the extracts of L. sulphureus and G. applanatum. It was observed that L. sulphureus extract caused dose-dependent inhibition of hyaluronidase, while all the extracts inhibited tyrosinase. The extract of G. applanatum exhibited an SPF value of similar to 9. Conclusions The results showed that the mycelial cultures of the studied species may be used as an alternative source of substances used in cosmetology.
